1lb all whom t 'may` concern:

Be it known that I, JAMES D. MOORE, a

citizen olE the United States, residinef ati` Northvvilkeslioro, in the county of Wilkes and Stateot' North Carolina, have invented` a new and useful Separatoryol which the tollowing :isa specification.

This invention zrelates to separators `de-` ot the machine.

`said shaft and is adapted to receive motion `through a belt 15 from a pulley 16 secured signed for use in the separation of grits from i bran and meal, one of the objects of `the invention being to provide a single blower and separate tlues receivingairtherefrom,

means being employed whereby currents of.V

dillerent velocities aredirected `through thel y y bottom thereotl are preferably three troughs respective lues to different parts ot' the:ap-

paratusso that bran can be separated from the grits Without losing the line grits.

A further object is to provide agitating means of novel form for preventing meal from lodging in the `separator' screen and interfering with the proper operation ofthe` machine.

With the .foregoing and other objectsin vievv which will appear as thedescription proceeds, the invention residesiin the combi i nation and arrangement of parts and,` in the details ol construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed,` can` bemade` vvithin the scope of `what is claimed, Without departing from the spirit oftheinvention."`

In the y accompanying drawings `the pre- :lerred form of the invention has been shown.

In said drawings Figure 1 is a vertical longitudinal sec-i` tion through the` separator` Fig.` 2 is a top plan view, certain of the parts being broken away.

Fig. 3 is a sectionon line AQ-#B Figi 1. y

`,Figa is a side elevation f of a portion d the machine. y Referring to the figures hycharacters ot reference 1 designates standards connected by cross beams 2 and `by sidebeams 3, `"each` side beam having a longitudinal inwardly extending flange `l constituting 4a.`guide Or` spacing element. One of the beams-3 `is en?` j larged from `top towbottom` l(aime "eiitl,` as shown at. 5, this enlarged portionbeing prof vided with a large opening i `livotally connected d, to and A from the upper portion of cash of the standards or posts 'l ,is hangerjvf andithesej hangers areall pivotally connected sides 'ot a `sieimze box, `8 y provideda nearwonen reccentric l2.

to a transverse drive shaft l'ijournaled upon said posts or standards 1 and which is adapted to be operated in any suitable manner. f i

Arranged transversely olE the box S` at the indicated at 18,19 and 20, respectively. The trough 18 is arranged between the down- `Wardly converging bottom portions 21 and Q2 of a hopperfQS extending.;` inwardly from one end of the box 8 and preferably overhang-ing the sha ft 13 `and the eccentric therex ion. i A deflecting lip 2411s extended down- Wardly 'from the upper end of the inclined i portionQl ot the bottom oil hopper Q3 and overhangs the middle trough 19. An imperforate incline Q5 extends upwardly troni that side of the trough 19 remote from the trough 18 and the upper end of this in oline overhangs the third trough 20. Air other inclinel extends upwardly from that side el trough 20 remote from trough 19 and merges, at itsupper end, into the bottom 27` of a discharge spout" 28 Within one end ofthe sieve box. The top of the dis` `charge spout is preferably formed of a curved" plate 29 secured upon the sides of y the box and extending throughout the Width of the box. d l

By `p"rovihaar spaced troughs 18, 19 and 20vvith the inclines extending from the trougln-i"191 andQO and the hopper extendu ing` above the trough 18, it will be apparent that tivo" air passages `3() andl are pro duced, the air passage `3() extending above thetroughflQ andincline 25, ivhile the pas sage. 3l extends above the trough 20 andineline 26. Supporting cleats 32 are secured tothe inner faces ot the sides of thebox 8 at the upper end ot' passageBO. Additional supporting cleats 33 are securedto the sides v olithelbox 8 `and attlie upper end of the passage 3l, these cleats 33 being disposed bel"` le'vv cleats"B2".` Additional supporting ele`ats`"`3/laresecured `to the `sides of the box` atthe of hopper These" dfie 134 @erstrahlt in ribadesella lle same plane as lthe cleats Detachably mounted on the cleats 33 is the frame 35` carrying a screen fabric 36 of coarse mesh so as to permit coarse grits to pass therethrough. This frame 35 is detachably mounted on the cleats 33 and the fabric 36 extends entirely across the passage 31 there being, however, a small outlet space between the upper end of the incline 26 and the outer end of the screen frame, as shown at 37. Longitudinal displacementof the screen frame is prevented by blocks 38 secured to the sides ofthe box 8.

The inner end of the screen frame abuts against the adjacent ends of the cleats 32 and is lapped by the frame 39 which carries a screen fabric 40 of sufficiently ne mesh to permit only tine grits to pass therethrough. This screen :fabric 40 extends across the upper end of the passage 30.

Extending entirely over the hopper 23 and resting on the cleats 34 is a frame 41 having superposed screens 42 'through which meal is adapted to fall into the hopper 23. Material passing from the inner end of each of the screen fabrics 42 is adapted to be received by the screen fabric 40, there being a lip 43 extending from the discharge end of the fabric 42 and lapping the frame 39. The frame 39 is held against displacement in one direction by the frame 41 and in the other direction by blocks 44 secured to `the sides of the box 8.

Extending over all of the screens and from one side to the other of the box is a frame 45 carrying a coarse fabric 46. This screen fabric 46 serves to prevent large par ticles of foreign substances from entering the separator.

Secured to the posts or standards 1 at the drive end of the machine is a blower casing 47 said casing being concentric with the shaft 17. The blower 48 is fastened to shaft 17. A flue 49 extends from the casing 47 and is forked near its upper end` one branch of the flue, which has been indicated at 50, being adapted to direct air into the passage 30 while the other branch 51 ex* tends under the trough .19 and directs air into the passage 31. plate 52 is formed integral with the top wall of flue 49 and extends into the passage 30 close to and under the inclined portion 21 of hopper 23, while another bowed deflecting plate 53 is formed integral with the top wall of the branch 51 and extends into the passage 31 close to the incline 25. The .flue

49 and its branches are not secured to the box 8 but are suitably supported by side connections 54 between the posts or standards 1, the detlecting plates 52 and 53 being i held stationary while the box S is moved under the action of the eccentric 12.

A damper 55 is pivotally mounted at the fork of flue 49 and is adapted to be adjust- A bowed deflecting ed angularly so as to regulate the discharge of air through the branch 59. This damper has an arm 56 movable therewith and said arm can be fastened in any desired manner so as to hold the damper 55 in any position to which it may be adjusted.

Each of the troughs 18, 19 and 2O has an outlet 57 extendingtherefrom at one end.

Extending under the screen 42 are oppositely disposed beaters or agitators 58 pref-A erably though not necessarily, bowed as shown in Fig. 2 and having end portions journaled in the sides of the box 8. One end of" each beater extends through the opening 6 in the main frame and terminates in av crank arm 59 having an inturned end 60 pivotally engaging the enlarged portion 5 in which the opening 6 is formed. The crank arms 59 extend in opposite directions and it will be obvious that `when the box 8 moves longitudinally relative to the side beams or connections 3, the beaters or agitators 5S will be caused to swing so as thus to tap upon the bottom of the screen 42 and loosen any material which may become lodged in the. meshes of the screen. Y

In using the appara-tus the shafts 17 and 13 are driven in any suitable manner so as to cause the blower 48 to revolve and the box 8 to reciprocate. Sufficient spaces are formed between the defiectors 52 and 53 and the inclines 21 and 25 respectively so that this relative movement will not be interfered with. After the parts have been set in motion the material to be separated `is directed onto the screen 46 so as to pass therethrough onto the screens 42. At this point the meal contained in the material will be separated from the grit and bran and will gravitate into the hopper 23 from which it will pass by way of trough 18 to the spout 57 extending from said trough. The beaters constantly act upon the screen 42 so as to keep the meshes open, as before described. The grits and bran pass from the screen 42 onto the screen 40. At this point only a light current of vair is directed against the material on screen 40, this being due to the fact that the damper 55 delects most of the air current into the branch 51, Consequently whilebran contained inthe mixture will be blown upwardly from screen 40, the air current will not be sufficiently strong toprevent the fine grits from passing downwardly through the screen,` These fine outwardly grits will fall onto the incline 25; VThe del flector 52 directs the air current transversely of the passage 30 so that it will strike the incline 25 and thus cause any bran which may pass through the screen 40, to be discharged upwardly along incline 25 Vand through the space formed between the upper end of .said incline and the inner end of the frame 35. The coarse grits and bran passing oli' ol screen a() will be discharged onto screen 3G and here met by a strong current of air passing from the branch 51 and through passage 31. Consequently, bran mixed with the coarse grits will be blown outwardlyT through the spout 28, while the coarse grits will gravitate onto the incline 26 and thence to the trough 20 from which they will be discharged through the spout 57 extending from said trough. The deflector 53 directs the current of air across passage 31 and against the incline 26 so that, should any bran fall through the screen 36, it will be met by this current and thrown outwardly through the space 557. By means of the damper 55 the relative velocities of the air currents discharged through the branches 50 and 51 can he varied.

It has been lound that by utilizing 4the lcilectors 52 and 53, any bran which may he adhering to the grits will be separated 'therefrom and blown :from the machine.

What is claimed is zl. A separator including spaced inclincs :forming an air passage therebetween, means at the lower end of the incline for receiving material gravitating therealong, a screen extending across the up 3er end of the air passage, a iue discharging into the passage and having its lower wall leading to a point close to the material receiving means, anV

arcuate deflecting plate constituting a con tinuation of the upper wall of the fine and over-hanging the material receiving means for directing air currents downwardly onto and upwardly along the incline, and means For directing an air current into the flue.

2. A separator including spaced inclines forming separate air passages therebetween, means at the lower end of each incline for receiving material gravitating therealong, screens extending across the upper ends of the air passages, a flue having branches discharging into the respective passages, the lower wall ol. each branch leadingto points close to the respective material receiving means, arcuate detlecting plates constituting continuations of the upper walls of the branch lines and overhanging the respece tive material receiving means for directing air currents downwardly onto and upwardly along the respective inclines, and means for directing an air current into the flue and its branches.

In testimony that I claim the foregoing as my own, I have hereto aiixed my signa ture in the presence of two witnesses.
